We start wet labs next week and I think I'm going to recommend either disposable masks for each lab or that students bring a cloth mask other than the one(s) they use in chemistry lab. That way if something transfers it stays in the lab room and they don't wear it out to the cafeteria at dinner time. For me, that's the same reasoning as not wearing your lab coat or apron outside of lab.--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchasCarl B.

I was worried that if a student got chemicals on the mask through some transfer from their hands and then kept wearing it after they left, they would be breathing the contamination.
So, we require and provide a new disposable mask for students (and faculty) in the labs to wear and dispose of before leaving. After washing their hands, they should put on their personal mask.
It may seem as overboard, but since the university was willing to pay for it, we are doing it.

Are reusable masks okay in lab or only disposable ones because of chemical contaminants?I'm not sure if you are thinking in terms of cloth or paper masks, but I would recommend that any masks that have been splashed on be replaced immediately. Cloth masks present similar challenges as other clothing worn in the lab. Paper masks are not likely to retain fumes, but also wear out fairly quickly. For that reason, new paper masks each class make sense to me.
